A deflection roller for guiding and/or deflecting a rubber tire component, has a shaft that defines an axis of rotation of the deflection roller and a plurality of bristles distributed circumferentially around the shaft and extending radially outwards and orthogonally with respect to the axis of rotation to form a circumferential brush surface that is concentric to the axis of rotation. The deflection roller further has a first boundary element and a second boundary element extending adjacent to the plurality of bristles in an axial direction parallel to the axis of rotation and protruding radially outside the circumferential brush surface at a first end and a second end of the circumferential brush surface, respectively, for binding the circumferential brush surface in the axial direction.
